Do I need a physical examination to travel to South Korea?

No physical examination is required. I went to Korea once with a group in 2008. I suggest you buy more Laneige cosmetics, facial cleansers, etc. there, they are very cheap. Much cheaper than at home. Then there's no bargaining on things over there, they just charge the price. I don’t know if you will go to Jeju Island, but the “Harubang” I bought when I was in Jeju Island. The tour guide said that it is a specialty of Jeju Island, so it is the cheapest to buy it in Jeju Island. If you go to Seoul, buy the ones from Korea. Drums and other specialties. You can also bargain when buying clothes in Dongdaemun, South Korea. Personally, I think the Korean BBQ is delicious, but I really can’t compliment the others. Bagged pickles in supermarkets are also a good choice to buy. You can buy a 777 nail clipper set, which is pretty good and easy to use. Hope this helps.
